Eva, I couldn't find a clip of Dina dancing to Fatme's version of this - though I'm certain she did, because it's on Fatme's "best of Saidi" CD which is the soundtrack for Dina's "Monte Carlo" show.
But here's Dina dancing to some speeded-up version of the song (NOT Fatme). I definitely have the impression that you're free to wear whatever you like for this one. Although...hmmmm...this is a dress....and for Dina, it's fairly conservative, even....
